tion of the mixing chambers with vrespect to the vfuel chambers and for supporting one upon the other. This means includes a pair of diainetrieally opposite arms 26Y slotted or bifurcated as at 27`and extending along'Y the mainfuel chamber. The arms are connected at one end to the shell 21 preferably by being formed integral therewith and are then offset so as to lie immediately adjacent' the fueljchamber. Threaded studs 28 are carried by the fuel chamber and project 1 Vthrough the slots 27 of the arms. Washers 29'an'd nuts 30 cooperate with the studs and armsto secure these partsin adjusted posi-y tion.

In,` operation, fuel such as gas issupplied tot-hemain fuel'chamber'll and. flows there-f throughV into the` Vauxiliary fuel chambers 12. The fuel is projected through the dischargeorifices 14V ofthe main fuely chamber t andv through-the discharge; orifices, 160i kthe auxiliary, fuel chambers.

The jets of fuel projected-through the-,discharge orificesglfl entrain the air and induce a fiowythereof through theair inlet opening andthe jets of fuel yfromthe discharge openings 16 entrain the air in the shell 23: and-,induee an inflow of air throughthe inlet openingl The-moving column of .partially :mixed air Y land fuel` proceeding through and from the shell 21 meetsV the incoming airo'fthe inlet openingg25` andcomminglestherewith and theny proceeds into theshell 23 in whichl the mixtureis agitated by` the jets offuel fromv thevjorifices 16 and in Awhich a'complete, uniform, thorough and efiicient mixture isenl -gendered as a resultofthe action previously described and of the formation ofthe shell 23. y Thus when the'gas is ignited therewillv beca` complete and efficient combustion and a Ahigh generation and levolution of heat.
